Writing statistics

How much do writers write per day?

The documented routines of famous authors are narrower than the legends suggest — most lived between 500 and 2,000 words a day, held daily.

For readers on the other side of the page: adults silently read English at 238 words per minute for non-fiction and 260 wpm for fiction — a meta-analysis of 190 studies with 18,573 participants (Brysbaert, Journal of Memory and Language, 2019). And forming a daily habit takes a median of 66 days, not the mythical 21 (Lally et al., UCL, 2010) — more on that in our writing habit guide.

Everyone wants to write a book. Who finishes?

The honest answer: nobody has measured "finishing" for writers at large — but the fragments that exist are telling.

"81% of Americans feel they have a book in them" comes from a 2002 New York Times op-ed by Joseph Epstein ("Think You Have a Book in You? Think Again"). Epstein cited "a recent survey" — attributed to the Jenkins Group — whose methodology was never published. Quote it as a famous claim, not a research finding.

Real surveys are more modest. In a 2021 OnePoll survey of 2,000 Americans, 55% thought their life was worthy of a book — but only 15% had ever started writing one, and just 6% made it halfway (OnePoll for ThriftBooks, 2021). In the UK, being an author is the single most desired job: 60% of Britons would like to be one (YouGov, 2015).

The best hard completion data ever collected comes from NaNoWriMo, where hundreds of thousands publicly committed to a 50,000-word draft in a month. In 2013, of 310,095 participants, 14% finished; the average participant wrote 11,352 words (official stats, archived). In 2018, 287,327 started and 35,387 won, averaging 22,871 words (official stats, archived). The nonprofit behind the event shut down in 2025, which makes these numbers a closed historical dataset — the pace math lives on in our NaNoWriMo calculator.

The first novel, in numbers

The largest survey of professionally published novelists (247 authors, Jim C. Hines, 2010) found:

• Authors wrote for an average of 11.6 years before selling their first novel (median: 10 years).
• The average debut author was 36 years old at the first sale (median 36, mode 37).
• 47% sold their first novel with zero prior short fiction sales (116 of 246) — the "publish stories first" path is optional.

Planning your own first draft? The writing time calculator turns a word count and a daily pace into a finish date, and word counts by genre shows what length agents expect.

Publishing odds, without the folklore

In 2025, more than 4 million books with ISBNs were published in the US — 642,242 from traditional publishers and over 3.5 million self-published: about 5.5 self-published books for every traditional one (Bowker via Publishers Weekly, 2026). Self-publishing first crossed a million titles a year back in 2017 (Bowker, 2024).

Agents who publish their own numbers describe funnels like ~5,000 queries a year → ~50 manuscript requests → ~10 new clients — roughly 0.2% (agent interviews collected by Darling Axe).

And sales: real BookScan data on 45,571 new titles from the top-10 US publishers over 52 weeks showed about 66% sold fewer than 1,000 print copies, 14.7% sold fewer than 12, and under 2% passed 50,000 (Kristen McLean / NPD BookScan, 2022).

Advances: in the crowd-sourced #PublishingPaidMe dataset the median reported advance was $18,750 (2,500+ self-reported figures, all career stages — LA Times, 2020); the only methodical debut survey, in SF/F, found a median first-novel advance of $5,000 (Buckell, 2005–07 — dated but still the cleanest debut data).

What authors actually earn

Two trends inside those numbers: established self-publishers (publishing since 2018) reached a $24,000 median — up 76% in four years, while UK author earnings fell 38.2% in real terms between 2018 and 2022, with only 19% of authors living on writing alone (down from 40% in 2006). A June 2026 Authors Guild–sponsored study pegs average US author earnings at about $10,000 — down roughly 42% since 2009 (Codex Group via Publishers Weekly, 2026).

AI & writing, by survey

• 23% of writers used generative AI in their process in 2023, and 90% said authors should be compensated for AI training use (Authors Guild, 2023, n=1,700+).
• 45% of (mostly indie) authors used generative AI by May 2025 — and 74% of users don't disclose it to readers (BookBub, 2025, n=1,229). Different sample than the Authors Guild's — the pair shows the spread, not a trend line.
• 36% of translators and 26% of illustrators reported already losing work to AI (Society of Authors, UK, 2024, n=787).
• Asked about licensing their books for AI training, 62.8% of indie authors said no amount of money would be enough if the AI would compete with human authors (Draft2Digital, 2024).
• On the reader side, 61% of US adults would feel less fulfilled learning a book was written by AI, and 56% want AI contributions disclosed (YouGov, 2025).

Famous numbers nobody can source

Every listicle about writing statistics leans on the same handful of dramatic numbers. We spent a day trying to trace each of them back to something real, and in every case the trail went cold. Here is where it actually leads.

• "97% of people who start a book never finish it." This one has travelled from blog to blog for over a decade, usually credited to a 2003 survey by the Jenkins Group, a Michigan publishing-services firm. The earliest traceable appearance is a 2011 Mental Floss article, which the magazine later amended with a note admitting it could not establish where the numbers came from. Jenkins Group itself has publicly said the viral statistics circulating under its name were never its research. It is also worth asking how anyone would measure this: there is no registry of started books, and there never has been.
• "Half of all books sell fewer than 12 copies." This claim went viral during the 2022 antitrust trial between the Department of Justice and Penguin Random House, when a stray courtroom exchange was stripped of its context. When a BookScan analyst reconstructed the real distribution across 45,571 new titles from the ten largest US publishers, the share that sold fewer than a dozen print copies came out at 14.7 percent (see Publishing Odds). That is a sobering number in its own right, just not the apocalypse that made the rounds.
• "Only 1 in 6,000 queries gets a literary agent." Nobody has ever collected that dataset. The figure looks like an extrapolation someone once made from the inbox of a single busy agency, repeated as gospel ever since. The agents who actually publish their annual numbers describe a different, still brutal, reality: about five thousand queries a year, fifty manuscript requests, ten new clients. That works out closer to one in five hundred.
• "The average book sells 250–300 copies a year." Every version of this stat cites "a Publishers Weekly survey" that, as far as we can tell, no one has ever seen, linked to, or dated. Averages are also the wrong lens for book sales, where a handful of bestsellers drag the mean far away from the typical title. The verifiable BookScan distribution above tells that story more honestly.
• "UNESCO says 2.2 million books are published worldwide every year." UNESCO has no such publication. The number appears to descend from aggregations made in the 1990s and has been reprinted with a fresh coat of authority ever since. The closest checkable figure today is an aggregate of national statistics, collected in different years, that lands around 2.7 million new titles a year. Even that comes with a caveat: no standardized global count exists.
• "Manuscripts die at 15,000–25,000 words." A real observation, but a personal one. The phrase traces back to individual writers describing where their own drafts tend to stall, most famously a blog post about the "25,000-word death zone" in one novelist's early projects. No study has measured where abandoned manuscripts actually stop, which makes this an honest anecdote wearing a statistic's clothes.

Sources & method

Every statistic on this page was verified against the linked source at publication time — we fetched each page and confirmed the figure in its text. Numbers we could not verify were either dropped (Mark Twain's daily counts: primary pages unreachable) or moved to the folklore section above. Survey figures carry their year; samples differ, so compare with care. Last updated July 26, 2026.
